Be it known that l, Sonn -l, Henson, s citizen of the United States, residing-ot Chi ooge, in the county oi" Cook and State or' lllinois, lieve invented certe-in new ond useful Improvements in Eleotrio ire Insulators, of which the following is e specification., My inventionrelates to eleotrioovireinsulaters, end more particularly to orossover inf sulators 'for insulating from each other orossing Wires forming port of en electric eirouit or oireuits. n

@ne of the prirnery objeotso'f'rny invention is to" provide e devies lof the onere-eter .de-scribed,A of one niece construction, which rney be eosny enti oheginly inode, which is simplein construction, easy of eppliostion to wires already strung, and elieient in operation.

Throughout the drawing like numerals of reference refer always to like parts.

ln the embodiment of my invention illustretefl, l provide e body of insulating mote-- rial, prefersblye singlevpieoe of porcelain or glass, comprising n central insulating portion 5, which l nioyterin the senereting ortion, lying in. e central lone, andyprovidee on opposite feces with needs, numbered 7, 8 end 7', 8, the heads 7 ond S being on one ieee of the central separating portion, and the heads 7 snd'S being on the opposite ieee thereof. Considering the heads '.7 and 8, they ere disnosed in diagonally opposite areas oi' the ieee troni which they protrude, with their proximote sides along one line, separated to lesive therebetween a Wire entrance groove 9, pref-A erobly straight, transversely or the ieee, end straight vertically of the foce, so that e Wire leid straight along one medien transverse line of the'fsce may pass down Without dis- .the entrance groove .i

l0', constitute-d by the coacting heads 7 and 8 is at the same re ative angle to channel l0, and further the heads 7 and 8 are in the diagonal areas of their face of the article, which underlie the plane corners 12 and 13/ of the opposite face, or otherwise stated, the heads on one side are in quartering relation to the heads on the other side. Further it will be observed that all of the channel-parts 10 and 10 open in like direction with respect to the imaginary vertical axis of rotation of the article, Now it will be apparent that my improved insulator may a-11, and c-d, already tightly strung and fastened in crossing position. To this end an insulator having its grooves disposed relative to each other at proper angles approximating the angle of the crossing wires, is forced between the crossing wires in such position that the wires may spring into the entrance grooves 9, 9, and then the structure'is rotated on its imaginary vertical axis, forcing the obstructions 14 past the wires and seating the wires in the respective receptacles 10 and l0', which are also in the proper angular relation to each other. Now the wires are retained in separated relation, and thev insulator is supported wholly from the wires, rotary movement of the insulator relative to the wires being prevented by the obstructions' le, and vertical displacement being prevented by the overhanging and overlapping lips 1l. While I have herein described in some detail a specific embodiment of my invention, which I have found to be convenient in its specific4 construction, I do not desire to be understood as limiting myself, to the particular, configuration herein shown 'further than as specified in the claims.

. Havmg thus described my invention, what I claim and desire to secure by Lettersiatnt, of the United States, is: A

l. In a cross-over insulator, a body-of insulating material com rising a central separating portion provi ed on opposite faces with overhanging heads, the heads on each face being disposedl in and covering only diagonally opposite areas of said respective faces, the pair of heads protruding from one face being located at substantially. right angles to the pair of heads of the other face, the heads of each face separated along an intervening line by an entrance groove, and along aline at an angle to-such entrance groove, providing complementary` portions of a wire rece tacle vertically restricted by an overhanging ead portion to retain the Wire, such reception portions respectively opening'toward opposite ends of the entrance groove. l 1

2. In a cross-over insulator, a body of insulating material comprising in a central plane a solid separating portion, and on oparts of the .I

posite faces thereof separated overhanging l on. opposite faces of the separating portion being disposed at an angle relative to each other.

3. In a cross-over insulator7 a body of insulating material comprising in a central plane a' separating portion, on each of the opposite faces thereof, separatedheads located in and covering only diagonally opposite areas of the face, the heads on each face being disposed along one separating line to leave therebetween an entrance groove, and along the other separating line sha ed to constitute a wire receptacle vertica y overlain by portions of the head, and laterally open toward the plane areas of the separatin portion, such lateral opening being partialIy obstructed, and the grooves and receptacles, on opposite faces of the separating ortion of Ithe ody being disposed at an ang e relative to each other. p

4. In a wire holding device, a body of insulating material, providing on one face two diagonally opposite heads, each head covering ,substantially one fourth of the area thereof the heads being separated along one linev by a straight entrance groove, and along a line at an angle to such entrance groove providing complementary portions of a Wire receptacle vertically restricted, and laterally opening toward the plane portions of the -body adjacent opposite ends of the entrance groove, and obstructions for resisting the lateral egress of the Wire from such receptacle portions.

5. In a cross-over insulator, a central separating portion having on each face thereof two heads, the heads on each face being located on and covering only diagonally opposite areas of such face, and along one separating line disposed tolleave therebetween a substantially straight entrance groove, and along the other separatingline providing oppositely opening lateral channels constituting complementary parts of a wire receptacle, the heads on one face 'of the insulator being disposed in the diagonal areas, which are planeupon the other face, and all of the laterally open channels opening in the same direction with respect to an imaginary vertical axis of rotation.

'6. In a cross-over insulator, a ortion 5, overhanging heads 17 and 8 protru ing therefrom on diagonally opposite areas thereof and obstructing knobs 14 to prevent the ac- I obstructing knobs located inthe front of the cidental displacement of the Wires.- securing portions of each head. l0 7.
